RING-MAKING MACHINEI SPECIFICATION forming part of Letters Patent No.778,472, dated December 27, 1904.

Application led April l5, 1903. Serial No. 152,718.

To HN '1l/7mm, t 711mg/ concern;

Be it known that I, OTTO S. BEYER, a citizen of the United States ofAmerica, and a resident of East Rutherford, county of Bergen, and Stateof New Jersey, have invented certain new and useful Improvements inRing-B/Iaking Machines, of which the following is a specification.

My invention relates generally to wire feeding and bending machines, andhas more particularly reference to wire-ring-making machines.

The special object of my invention is to produce a structure capable ofadjustment to form one or more wire rings of variable sizes during' acertain period from a strand of wire fed substantially uninterruptedly.Other objects will appear as the specification proceeds; and to this endmy invention comprises the features of construction and arrangement ofparts, as will be more fully hereinafter described.

I shall describe a wire-ring-making machine embodying my invention, andafterward pointent the novel features in my claims.

In the drawings I have shown my invention in one form; but changes ofconstruction may of course be made without'departing from the spirit ofmy invention.

In the said drawings, Figure 1 shows afront view of a machine embodyingmy invention. Fig. 2 is a side view of the same. Fig. 3 is a sectionalview, on the line a a' of Fig. 5, of the clutch mechanism for operatingthe feed-rolls. Fig. 4 is a detailed view of part of the said clutchmechanism. Fig. 5 is a rear view of the machine. Fig. 6 is a side view,partly broken away, of one of the clutches shown more particularly inFig. 3. Eig. 7 is a plan view of the feed-rolls and wire-bendingmechanism. Fig. 8 is a vertical sectional view through the cuttingmechanism. Fig. 9 is a plan view of the wire-bending mechanism, showingthe parts adjusted to form a smallersize ring. Fig. 10 is a view inelevation of the cutting mechanism.

Similar characters of reference denote corresponding parts in thedifferent Views.

1 indicates a framework in which the parts are properly mounted.

2 denotes two wire-feed rolls of any suitable construction, and 3wire-straightening mechanism of a well-known character.

4 denotes the means for forming the wire supplied into rings, comprisingin the present instance three rolls 5, horizontally disposed adjacent tothe feed-rolls.

6 is a cutting mechanism.

The wire is fed uninterruptedly, or substantially so, and the wire-feedrolls are adapted to feed a variably-predetermined length of wire in acertain period. To correspondtherewith, the means for forming the wireinto rings are made adjustable to form one or more rings of variablesizes out of the predetermined length of wire in the same period. Thecutting' mechanism is also adjustable and is adapted to cut off the wireafter the proper length has been fed and to act a number of times in theperiod it takes to feed a predetermined length of wire equal to thenumber of rings formed. The driving' mechanism for effecting theseseveral movements may of course be widely varied. In its preferred formthe construction is as follows 7 denotes a power-shaft having thepulleys 8 and 9 and provided with the pinion 10, meshing with the gear11.

12 is a sector mounted in the framework for driving the feed-rolls. Thissector is operated from the gear 11, which latter serves as a crank bymeans of the rod 13, fastened to one end to the said sectorl andadjustably secured with its other end on the crank or gear 11 by meansof the adjustable screw 12C By this means the stroke of the gear-sectoris varied.

14 is a shaft mounted in the framework carrying the lower feed-roll 2and provided with the gear 15, engaging with the gear 16 of the otherfeed-roll 2. This shaft is operated uninterruptedly from the gear-sectorby means of a clutch mechanism, so that the sector will operate the saidshaft 14 in the same direction on both the upward and downward stroke ofthe said sector.

17 and 18 denote two pinions mounted loosely on the shaft 14, the sectorengaging the pinion 17 direct and operating' the pinion 18 through theinstrumentality of the pinion 19 and gear 20, carried by the shaft 21,the said sector engaging the pinion 19 and the gear 2O engaging thepinion 18.

22 and Q3 are two clutches of the same construction, but with theelements reversed. Only one of these will be described. The pinion 18 iskeyed to the cup-shaped collar 24, mounted loosely on the shaft 14,having a hardened inside surface 25.

26 is a cam-ring mounted inside the collar 24 and attached to the sleeve27, fast on the shaft 14. This cam-ring is provided with a number ofcam-surfaces terminating at one end in a recess 28 and at the other endin an incline 29. Mounted loosely on the sleeve 27 is an outer member30, having projections 31 extending into the space formed between thecup-shaped collar 24 and the cam-ring' 26. ln this said space resting onthe cam-ring and between the projections 31 of the outer member are aplurality of rollers 32. A spring 33 is connected at one end of theouter member and at its other end to the sleeve 27. On the downstrokethe sector will drive the pinion 18 in the direction shown, carrying'the cup-shaped collar 24 with it. This has the effect of moving therollers 32 up to the ineline 29, thereby jamming the parts, andconsequentl y carrying the sleeve 27 with it, whereby the shaft 14 isrotated. When the sector moves upward, the spring' 33 will pull theouter member 30 with it, so that the projec tions 31 will carry therollers 32 `into the recesses 28, while the action of the sector willcause the cupshaped collar 24 to travel inthe opposite direction of theshaft 14, the said cup-shaped collar escaping' past the rollers 32,owing' to the fact that they are in the recesses 28. At the same timethe sector is operating the members of the other clutch to drive theshaft 14 in the same direction previously, so that the said shaft isoperated continuously or uninterruptedly in one direction. By regulatingthe stroke of the sector the amount ofthe wire fed in a certain periodor with each stroke of the sector can of course be variablypredetermined.

The three ring-forming rolls 5 are mounted on the bracket 34 and areadjustably secured to the same in the slots 35 by means of theset-screws 36, so that different sizes of rings can be formed.

The cutting' mechanism 6 in the presentinstance comprises acutting-knife 37, mounted on a vertical stem 38, working in the guide39, pivoted in the ears 40 of the support 41, which latter is adjustablymounted in the sleeve 42, secured to the position by means of the screw43. The shaft 44 of the gear 11 carries a cam member 45, comprising acollar 4G, having' a sidewise-projecting lug 47 and a cam-support 48,mounted adjacent to the same and provided with the set-screws 49,adapted to be tightened against the lug 47, and wherel, by also the saidcam-support can be adjusted circumferentially on the shaft 44. Thecamsupport carries a number of removable cams 50. in the presentinstance two. These cams act on the rod 51 in the support 41, having ahead 52, which prevents downward displacement and which engages with thestem 38 to operate the cutting-knife. The guide 39 has a passage 53.throug'h which the wire passes from the ring-forming rolls, and furthercarries an extension 54, resting on the boss 55 of the support 41 andpressed thereag'ainst by the spring' 56. By this means the cutting'operation will not interfere with the uninterrupted feeding of the wire,as the g'uide 39 will follow the feeding motion of the wire while it isbeing' cut by reason of its pivotal connection with the support 41 andwill return to its proper position by means of the spring 56. This playof the cutting mechanism is indicated in dotted lines in Figs. 7 and 8.The spring 57 returns the stem 38 to its downward position after it hasbeen lifted by the rod 51.

From the foregoing' it will be understood that the wire is feduninterruptedly, but that a variablypredetermined length can be fed witheach complete up-andsdown stroke of the sector. The driving mechanismfor the feed-rolls and for the cutting mechanism are so related thatwith each complete stroke of the sector the cutting mechanism acts anumber of times equal to the number of rings desired. By removing one ofthe cams 50 it will act only once in each period and by retaining' bothit will act semiperiodically. By adjusting the wire-forming rolls 5 toform into a ring a length of wire equal to the leng'th of wire cut offdifferent sizes of rings can of course be obtained, or several rings ofan equal size can be formed in each period. The support 41 must ofcourse also be adjusted in the sleeve 49 to correspond to the adjustmentof the rolls 5, and when only one ring is formed in each period thecircumferential position of the cam-support will be suitably adjusted tocause the cutting' device to operate at the proper time, depending' uponthe size of the ring desired. /Vith this arrangement no matter how themachine is adjusted no time will be lost by the moving parts; but themachine will turn out rings uninterruptedly.

A plate 58, having' an inclined portion 59, is located adjacent to thering forming and cutting mechanisms to cause the forward end of the wirering to travel up above the wireforming rolls.

The operation of the machine is as follows: The wire passes through thewire-straightening` mechanism, through the feed-rolls to thering-forming rolls, and into the passage 53 to the wire-cuttingmechanism, where it is cut oli1 at the proper moment, after which it isdis posed of in some suitable way.
